BURNER.

Application filed November 15, 1915.

To all whom it may concern:

Be it known that I, BENJAMIN C. BARTLE- BAUGH, a citizen of the United States, residing at Wheeling, in the county of Ohio and State of .Vest Virginia, have invented certain new and useful Improvements in Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in gas burners for use either on heating or cooking stoves.

The primary object of the invention is to provide a burner of this character so constructed that a maximum quantity of air is fed with the gas fed to the burner, thereby insuring perfect combustion.

Another object is to construct a burner of this character so that the gas will be fed to the mixing chamber thereof with great force thereby carrying with it a large amount of air which causes a perfect mixing of air and gas in its passage to the burner proper thus assisting in producing perfect combustion.

Another object is to provide a burner with a mixing chamber having adistributing partition therein whereby gas and air is mixed a second time before admission.

Another object is to provide a burner having a plurality of rows of outlets on the top, said rows being arranged in series and the series spaced apart for he purpose of forming inlet channels for he air supplied to the flame while burning to assist in producing perfect combustion, and by means of which a flame is produced which destroys all poison which is contained in the gas such as carbon monoxid, all of the gases being consumed and thereby prevented from passing out to the surrounding atmosphere.

Another object is to provide a burner having a mixing chamber provided with inlets arranged to discharge thereinto in opposite directions to cause the streams passing therethrough to forcibly meet and thereby thoroughly mix the air and gas of which they are composed.

IVith these and other objects in view, my invention consists of certain novel features of construction, and the combination and arrangement of parts which will be hereinafter more particularly described and claimed.

Serial No. 61,612.

In the accompanying drawings: Figure 1 1s a side elevation of a burner constructed in accordance with this invention; Fig. 2 is a on the line 4l of Fig. 2; Fig. 5 is a similar view taken on the line 55 of Fig. 2; Fig. 6 is a similar view taken on the line 66 of Fig. 2; Fig. 7 is a side elevation partly in section showing another form of burner; Fig. 8 is a transverse vertical section taken on the line 88 of Fig. 7; and Fig. 9 is a transverse horizontal section taken on the line 99 of Fig. 7.

The improved burner shown comprises an outer cylindrical casing 1 closed on all sides and at both ends, the ends of the cylinder being here shown extended outwardly in the form of a flange 2 over which the edges of the end closures 3 are crimped as shown clearly in Fig. 2. The upper or top portion of this casing is provided with a plurality of series of laterally spaced rows of perforations 4 extending from end to end of the burner, the space 4 between said series being designed to admit fresh air to the burning gas which passes through the perforations of each series, said perforations being designed to discharge gas from the burner, two series being here shown although obviously any desired number may be employed. This cylindrical casing .1 is shown provided in its bottom wall or the wall diametrically opposite the perforated wall thereof with an opening 5 for the admission of the fuel to the cylinder 1 in the form of air and gas as will be hereinafter more fully described. This lower wall is slit longitudinally and ransversely and the slit portions thereof bent to form the side walls 6 of a mixing chamber 7 to be described. As shown, this chamber 7 extends about one-half of the length of the cylinder 1, more or less, being spaced inwardly at its opposite ends from the opposite ends of said cylinder. As shown, the cylinder 1 is provided at its ends beyond the ends of the mixing chamber 7 with insets 8 and 9 which are here shown connected to the slit portions of the cylinderby crimping, (see Fig. l). These insets 8 and 9 are in the form of laterally curved longitudinal extensions of semicylindrical shells 1 and 1 which are disposed within the casing l opposite the perforations therein. These shells l and 1 have the extensions 8 and 9 formed intermediately of the width thereof preferably midway, as shown in Figs. 2 and 3 and the inner opposed ends of said shells are spaced apart to form the fuel inlet 5. The side edges of these shells are positioned to form supports for a horizontal partition 11 to be described, and are offset inwardly to form pockets 1 to receive flanges on said partition. These shells perform the double function of supports for the partition 11 and as reinforcing and strengthening means for the central portion of the casing 1. They also provide a closure for the slit wall of the casing and as means for forming the opening 5 of the desired size, the distance between the inner ends of said shells controlling the size of said opening.

The bottom wall of the mixing chamber 7 which is here shown cylindrical but may be of any other desired cross sectional contour, is formed by inserting a longitudinallyextending strip 10 which is here shown extended the full length of the chamber 7 and is crimped to the edges or the outwardly bowed side Walls 6 thereof by crimping.

Arranged within the casing 1 is the longitudinally extending horizontally disposed partition 11 which is disposed between the series of perforations 1 and the opening 5 and which extends over said openingand projects beyond the end walls thereof. This partition 11 is shown provided on its opposite side edges with right angular depending flanges 12 which may be secured to the'opposed side walls of the cylinder 1 by soldering orin any other suitable mannerfsa'id partition being here shown supported by the edges of the shells 1 and 1 as above'd'escribed, said edges being shown offset inwardly as at 1 forming pockets to receive the flanges 12. This partition 11 is designed as a deflector or distributer for the air and gas admitted through the opening'5 which impinges against said partition and spreads outwardly toward the opposite ends thereof becoming thoroughly mixed in its passage and then passes up around said ends into the space between said horizontal partition and the perforated top of the cylinder and the so mixed air and gas then passes out through the perforations 4 where it is ignited and forms the flame of the'burner.

The mixing chamber 7 is here shown provided at its opposite ends with truncated cone-shaped inlet pipes 13 with the smaller ends of said pipes extending into the chamher 7 as is clearly shown in Fig. 1. These members 13 are designed to form inlet nozzles for discharging into the mixing chamber lair and gas, the gas being fed thereto through tips or spuds 14 arranged in the larger outer ends of said'cone-shaped inlets. These spuds 14 are mounted on branch pipes 15 which are connected with a main gas supply pipe 16. As shown, these spuds 1e are mounted in U-shaped brackets 17 V which span the outer ends of the cone-shaped inlets 13, and the free ends of the legs thereof are secured to said inlets and to the outer ends of the mixing chamber '7 by bolts or any other suitable fastening elements which assist in retaining said cone-shaped inlets in position within the mixing chamber 7. said members 13 being here shown as provided at their outer ends with flanges 13 which are crimped around the outer ends of the casing forming the mixing chamber 7 As shown, the spuds 14 are made in the form of reduced extensions mounted on threaded pipes 18 and which are secured to the brackets 17 by clamping nuts 19 disposed on one side or face of the bracket and a shoulder 20 carried by the pipes 18 arranged on the outer faces of said brackets as is shown clearly in Fig. 2. These spuds or tips 1% are mounted on the free ends of the branch pipes 15 which are here shown in the form of U-shaped couplings which are connected with the main pipe 16 by extensions 15 which extend laterally in opposite directions from said main pipe 16 so as to position said U-shaped pipes 15 at the ends of the mixing chamber 7 with the spuds disposed in position at the mouth or larger ends of the inlet cones 13.

Each of the spuds 14 is provided with a gas valve 21 which is shown formed of a screw threaded rod having an actuating handle at its outer end and which extends through the spud 14 and is designed to control the flow of gas through the opening of said spud. 7

From the above description it will be observed that a burner is produced provided with a plurality of air inlet and mixing cones which discharge in opposite directions into a mixing chamber 7 and the air and gas entering therethrough in opposite directions, meet substantially midway the length of the chamber 7 and the two streams impinge against each other becoming thoroughly mixed before passing out through the opening 5 into the cylinder 1 below the distributing or baffle plate 11 where it is further broken up and mixed before passing out around the ends of said plate from which it passes through the apertures 4 to the outside of the burner ready for ignition. The plurality of rows of outlets for discharging the gas from theburner which are spaced apart a sufiicient distance to provide for the drawing of fresh air into the space between them, provides forthe production of a flame which retains and consumes all of the poison such as carbon monoxid contained in the gas and hence insures perfect combustion and avoids all danger of monoxid gas poisoning. The arrangement of the cone shaped inlets in the opposed ends of the mixing chamber 7 alsoprovides for the suction of a large amount of air into said chamber by the gas as it enters the cones through he spuds 14.

In the embodiment illustrated in Figs. 7 to 9, a slightly diflerent form of burner is shown although the principle of operation thereof is the same. This burner comprises a flame tube 1' here shown cylindrical in form and closed at both ends the same as in the form shown in the other figures. This flame tube or casing 1 is provided on its top or upper portion with a plurality of series of laterally spaced longitudinally extending rows of perforations 45 here shown extending from end to end of the casing, the space 43 between said series being designed to admit fresh air to the burning gas in the same manner as that described relative to the burner shown in the other figures. This cylindrical casing 1 is shown provided in its bottom wall or the wall diametrically opposite the perforated wall thereof, with a plurality of longitudinally spaced inlets as 5, three of which are employed in the structure here shown and arranged in longitudinal alinement, although obviously any desired number may be employed. These inlets as 5 are designed for the admission of the fuel to the cylinder 1 in the form of air and gas as will be hereinafter more fully described. Extending laterally from the casing 1 with their smaller ends engaging the openings 5 is a plurality of cone-shaped mixing chambers 7 to the larger ends of which are secured gas supply pipes 22. These pipes 22 are shown mounted in brackets 23 connected with the mixing chambers 7 at diametrically opposite sides to provide sufficient space at the ends of said chambers for the free passage of air thereto. These pipes 22 as shown are substantially L-shaped with one arm thereof connected with a main supply pipe 24. The arms of these supply pipes which extend into the chambers 7 are provided with spuds 14; similar to those shown and described in the other figures and each of which is provided with a gas valve 21 for controlling the flow of gas through the opening in the spud. Arranged within the casing 1 between the inlet 7 and discharge openings thereof, is a longitudinally extending horizontally disposed partition 11 which is shown provided on its opposite side edges with right angular attaching flanges 12 which are held in engagement with the opposed side walls of the cylinder 1 by means of the offset side edges of the shells 1 and 1 which are the same as those shown in the form above described (see Figs. 7 and 8). This partition is designed as a deflector or distributer for the air and gas admitted through the openings 5 which impinges against said partition and spreads outwardly toward the opposite ends thereof in the same manner as in the form shown in the other figures, passing out through the openings 4* in the top thereof where it is ignited and forms the flame of the burner.

Applicant by employing a plurality of cone-shaped mixing chambers provides for the admission of a maximum quantity of air with the gas admitted through said chambers so that perfect combustion by the burner is insured.
